Filter by:Chronic volume overload (VO) is a primary factor responsible for the excessive cardiovascular morbidity and mortality in hemodialysis (HD) patients. VO is caused in part by excessive fluid intake that is secondary to the consumption of a high salt diet. HD patients are often counselled to restrict their dietary sodium intake to help manage thirst and reduce their interdialytic weight gain (IDWG). However, data from recently published investigations demonstrate that dietary counseling alone may be ineffective. The objective of this randomized controlled trial is to determine if short-term feeding of low-sodium meals can "prime" changes in long-term nutrition behavior. It is hypothesized that feeding low-sodium meals for one month will significantly reduce IDWG and related outcomes, and continued dietary counseling and education support for 6 months will result in a sustained reduction in sodium intake upon patient resumption of meal responsibility. HD patients will be recruited and randomized to 2 groups: 1) Low-sodium meal feeding plus dietary counseling; or 2) a weight-list control group that will initially receive dietary counseling alone. IDWG will serve as the primary outcome with fluid volume overload, intradialytic hypotension, cramping, dietary sodium intake, sodium taste sensitivity and preference, and sodium self-efficacy evaluated at 1 and 6 months. This outcomes of this investigation will provide the first data on whether meal provision is an effective tool for dietary modeling and prolonged behavior change in HD patients.
Cardiovascular morbidity and mortality is increased in kidney transplant patients. High blood pressure (BP) contributes significantly to this risk and is also associated with shortened allograft survival. Salt reduction lowers BP in the general population and there is emerging data that salt reduction also effectively lowers BP in chronic kidney disease (CKD). Kidney transplant patients, by definition have CKD, but they differ fundamentally from the general CKD population in that they are on medications which can predispose to high blood pressure, their kidneys are denervated, and they often have reasonable excretory kidney function. The proposed study will be an eight-week randomised, controlled trial assessing the effect of intensive dietary salt advice on cardiovascular risk factors in kidney transplant patients. The primary outcome is office BP readings, with the effect on 24-hour ambulatory blood pressure, proteinuria, arterial stiffness and endothelial function being studied as secondary outcomes.
Sodium-adapted magnetic resonance imaging (23Na-MRI) studies have demonstrated that sodium accumulates in certain tissues, including the skin and skeletal muscle, but may be manipulated by lifestyle factors or therapeutic interventions such as a hemodialysis (HD) session. This tissue sodium accumulation is increased with age and in the presence of certain chronic diseases such as renal failure, and may contribute to the development of high blood pressure. It currently not known what the impact of dietary sodium consumption has on tissue sodium in HD patient's and on the subsequent risk of cardiovascular complications either acutely or chronically. The University of Illinois' Biomedical Imaging Center recently completed safety testing on a 23Na-MRI coil that they modified for measuring skin and muscle sodium levels in the lower leg/calf that will be used for assessing the impact of dietary salt restriction on tissue sodium levels.
Determine whether nutritional support with high protein ONS in adult oncologic patients in the first step of cancer cachexia - asymptomatic precachexia, influence on the toxicity of systemic therapy.
The investigators aimed at evaluating the effectiveness of probiotics ingestion in changing maternal microbiota and preventing gestational diabetes in overweight and obese women. To achieve these goals, obese (BMI> 30 kg/m^2) or overweight (BMI> 25 kg/m^2) pregnant women with risk factors were enrolled in the study and randomized to the supplementation with the probiotic VIVOMIXX® or with placebo. The endpoints of this study are to evaluate if the dietary supplementation with the probiotic VIVOMIXX® modifies the maternal fecal microbiota (bifidobacteria and lactobacilli) and related enzymatic activity (alkaline sphingomyelinase and alkaline phosphatase), and if this if this is linked to an improvement of the intermediate metabolism (positive Oral Glucose Tolerance Test at 24-26 weeks).
Early nursing nutrition intervention for outpatients in need of surgery - Objective - To investigate the feasibility and effectiveness of screening and an early nursing intervention on malnutrition in outpatients in need for surgery. - Design - Multi-centre cluster-randomised controlled early trial design (n=150 patients) - Intervention - Malnutrition screening (during outpatient clinic visit) and (in case of patients being ´at risk for malnutrition´ or being ´malnourished´), a nutrition care plan (including nutritional drinks and energy and protein rich meals) tailored to individual patient requirements - Comparison - Usual care (no nutritional care plan)
Patients with mechanical ventilation have shown improved weaning rates when enteral tube feeding high in EPA, GLA and antioxidants were fed to patients in the critical care setting. LTAC Patients on chronic mechanical ventilation will have decreased days an mechanical ventilation, decreased mortality rates and decreased organ failure when fed an enteral product high in EPA, GLA and antioxidants compared to an isotonic high fiber enteral nutrition product.
Our group has recently identified the association between gut-flora-mediated carnitine and phosphatidylcholine metabolism, specifically trimethylamine-N-oxide (TMAO), and cardiovascular risk. This study investigates the ability for dietary intervention to modulate TMAO levels.
The investigators evaluate if changing eating habits and introducing a correct lifestyle in women with BMI >25 Kg/m2 would improve unfavorable maternal-fetal outcomes associated with excessive weight gain (EWG) during pregnancy. To pursue these goals, eligible women are randomly assigned to no intervention (Control group) that receive only a simple nutritional booklet about lifestyle and healthy diet during pregnancy without explicit caloric restriction or the Therapeutic Lifestyle Changes Program (TLC group) that receive a caloric restriction (1500 Kcal/day divided in3 main meals and 3 snacks + 300 kcal/die for overweight or 200 kcal/die for obese women submitted to energy expenditure program) associated to a mild physical activity (30 minutes at least 3 days/week) The investigators use a tool that could easily and practically evaluate not only total GWG at term, but also changes in maternal body composition: the bioimpedance analyzer.
